Commands can now delegate to a running Arc API server instead of
executing in-process. Adds ExecutionMode, ServerDefaults, and
ClientTlsConfig to cli.toml parsing with CLI flag > config > default
precedence. The models list command fetches from GET /models when in
server mode, with mTLS client certificate auth when [server.tls] is
configured.

Sets up Tailwind v4 via @tailwindcss/vite, adds the full brand palette

a complete homepage with hero, feature grid, code examples, verification
section, multi-model section, observability, "Why Arc", and CTAs.

Replaces flat ModelInfo fields with nested sub-structs (ModelLimits,
ModelFeatures, ModelCosts) and adds family, training, and

Filter engine-internal keys (internal.*, graph.*, thread.*, current*)
from the context diff returned by SubWorkflowHandler, preventing child
run state from overwriting parent values. Pass the parent's preamble
into the child context so child workflows have awareness of what the
parent already accomplished.

ModelInfo already derives Serialize with matching field names, so the
manual json!({...}) mapping was redundant. Matches the pattern used by
every other paginated handler in demo/mod.rs.

The extract_status_fields function recognized "outcome" as a field for
detecting status JSON objects but never read its value — LLM responses
like {"outcome": "fail", "failure_reason": "tests failed"} were silently
ignored and the outcome was always Success.
Now extract_status_fields reads the outcome field to set the node status
and failure_reason to populate the failure detail. Also adds a fallback:
if no routing directives are found in the response text, the handler
reads status.json from the sandbox CWD (written by agents that prefer
file output over inline JSON). Response text always takes priority.

New `arc-exe` crate that runs agent tool operations inside ephemeral
exe.dev VMs via SSH. Uses two SSH connections: a management plane
(`ssh exe.dev`) for VM lifecycle and a data plane (`ssh vmname.exe.xyz`)
for command execution and file I/O.
Includes SshRunner trait with MockSshRunner for unit tests and
OpensshRunner for real SSH, with raw_mode for the exe.dev management
plane's custom command handler.

The active_stages map was only populated inside a TTY renderer guard,

resolve_clone_credentials was short-circuiting for public repos,
returning no token. This broke git push from the sandbox since push
requires authentication regardless of repo visibility. Always generate
an installation access token.

- Replace apt-get/NodeSource install (requires root) with direct Node.js
binary download to ~/.local (works as non-root daytona user)
- Run node install + npm install in single shell so PATH persists
- Add ~/.local/bin to PATH in env file and version check
- Fall back to stdout for error details when stderr is empty (Daytona
always returns empty stderr)
- Add e2e assertion that cli_stdout.log is written during poll
- Verified on Daytona with haiku: ensure_cli installs in 2s, full
workflow succeeds

AgentCliBackend now detects missing CLIs at runtime and installs them

Remove hardcoded default_model_for_provider() from arc-workflows and
default_model() from arc-agent, delegating both to the catalog via
arc_llm::catalog::default_model_for_provider(). Add claude-sonnet-4-6
to catalog and move "sonnet"/"claude-sonnet" aliases to it.

Sync cli_stdout.log and cli_stderr.log to stage_dir each poll iteration

Daytona's POST /process/execute blocks until all descendant processes
exit. The backgrounded claude process kept the API hanging, causing a
60-second HTTP timeout. Using setsid creates a new session so the child
is fully detached — the API now returns in ~200ms.
Also touch the event emitter during the poll loop to prevent the stall
watchdog from killing the stage while waiting for claude to finish.
Falls back gracefully on macOS where setsid isn't available (not needed
since the local exec implementation doesn't wait for grandchildren).

Apply the changelog guide across all entries: demote incremental
changes (endpoints, flags, syntax options) from hero sections to
categorized accordion footers (API, CLI, Workflows, Fixes,
Improvements). Combine related hero sections (e.g. three hook types
into one). Add "## More" heading above accordion sections. Group
sidebar navigation by month.

Daytona's POST /process/execute is synchronous and blocks until the
command finishes. Long-running CLI agent sessions (claude, codex, gemini)
cause HTTP proxy timeouts. Replace the single blocking exec_command with
a background launch + poll pattern:
- Generate UUID-based temp file paths to avoid collisions between
concurrent CLI nodes
- Disable sandbox auto-stop before launching (new Sandbox trait method)
- Launch command in background, capture PID
- Poll every 5s for exit code file
- Read stdout/stderr from temp files after completion
- Cleanup temp files

When a workflow runs on a Daytona sandbox, commits on the run branch
are lost when the sandbox is deleted. This pushes the run branch to
origin after each checkpoint so the full commit history is preserved.
- Upgrade GitHub App token permission from contents:read to contents:write
- Add refresh_push_credentials to Sandbox trait (default no-op)
- Store origin URL on DaytonaSandbox and configure push credentials after clone
- Implement refresh_push_credentials on DaytonaSandbox to rotate expiring tokens
- Add git_push_remote helper, called after each remote GitCheckpoint
- Add e2e test verifying the branch appears on GitHub after push

Replace append-based .env writing with mergeEnv() that upserts keys,
preventing duplicates when setup runs multiple times. Capture the GitHub
App slug from the manifest API response and persist it in TOML config
so we can construct installation URLs.

- Write provider API key to /tmp/arc_cli_env.sh and source it before
running the CLI tool (Daytona exec API doesn't support env vars)
- Add --verbose flag to claude command (required with -p + stream-json)
- Log cli_stdout.log and cli_stderr.log on failure for debugging
- Fall back to stdout in error message when stderr is empty
Known limitation: CLI backend on Daytona times out for long-running
claude sessions due to Daytona proxy execute API timeout.

- Collect provider API key env vars and pass them to sandbox exec_command
so CLI tools can authenticate in the sandbox environment
- Wire up previously-ignored env_vars parameter in DaytonaSandbox, explicitly
set all ExecuteCommandOptions fields (catches new fields at compile time)
- Write stdout/stderr logs on CLI failure, fall back to stdout in error detail

- Skip start/exit nodes from all preamble modes (compact, summary high/medium/low)
- Exclude blank-string context values (e.g. failure_class: "") from context sections
- Emit section headers lazily so they don't appear when all content is filtered
- Exclude meta nodes from summary:high pipeline progress counts

The run.toml specifies a Dockerfile with node:22 + @anthropic-ai/claude-code

- CLI backend: show last 500 chars of stderr (not first), and include

- Test runner: add PARALLEL env var for concurrent execution
- backend-demo.dot: use API backend since claude CLI isn't in sandbox

The is_repo_public function called GET /repos/{owner}/{repo} with
the App JWT, but GitHub returns 401 for App JWTs on the repos
endpoint (they need an installation token). Previously this 401
was treated as an auth error, failing sandbox init.
Now 401 and 403 are treated like 404: assume private and proceed
to create an installation access token, which has the right perms.
Also add preflight phase to the DOT test runner.

Addresses agreed items from the openapi-hitl-and-run-outputs review:
rename retrieveRunDiff operationId, add 409s to steer/preview, bound
expires_in_secs, add selected_option_keys for multi-select end-to-end,
document skip/na semantics, add slug and require type on
RunVerificationControl, require file on CodeLocation, and remove the
